The bobolink (Dolichonyx oryzivorus) is a small New World blackbird and the only member of the genus Dolichonyx. An old name for this species is the 'rice bird', from its tendency to feed on cultivated grains during winter and migration. Adults are 16–18 cm (6.3–7.1 in) long with short finch-like bills and weigh about 28 g (1 oz). Adult males are mostly black with creamy napes and white scapulars, lower backs, and rumps. Adult females are mostly light brown with black streaks on the back and flanks, and dark stripes on the head; their wings and tails are darker. The bobolink breeds in the summer in Northern America, with most of the summer range in the northern United States. Bobolinks winter in southern South America, primarily Paraguay, Argentina, and Bolivia. Bobolink populations are rapidly declining due to numerous factors, such as agricultural intensification and habitat loss; they are considered threatened in Canada, and are at risk throughout their range.
